I acquired a marketing flyer published in 1983 that describes the top ~500 applications that were tested as compatible with the Columbia Data Product 1600 computer. It is quite interesting as it is a fairly comprehensive list of popular IBM PC software products at that time. The CDP 1600 was the first fully hardware compatible IBM PC clone, so it is also interesting from the perspective that clone makers were sort of sticking it to IBM. Clones of other platforms usually got squashed, and nobody really knew if IBM would crush the PC clone makers. It was very important for vendors to emphasize compatibility so that one would not regret buying their clone computer.

Winworld has a number of these. But as you can see, there are still many, many titles that are not archived.

Well, that is still very cool. I know they use a different motherboard form, but there is little information on how similar or not similar they are to the desktop 1600. As far as I know the VP's ROMs have never been publicly dumped, so I don't know how similar or different they are. (They might use the exact same ROMs).

In the 1983 byte magazine article announcing "Microsoft Windows", there are photos of "Windows" running on a variety of x86 computers, one of which is the Columbia VP.
